I’m not a clinician, but I can tell you that moodiness/agitation/aggression are common in three instances with ADHD medication:
1. Rebound, when medication is wearing off
2. When it’s not the right medication for that individual
3. Sometimes, if the dose is too low, it actually makes symptoms worse. It could be too high a dose too, but I think that more often shows in increased anxiety or “zombie” effect.
Talk to the prescribing doctor about which of these could be the case and what you can do about it.
